Doctor Strange's Sanctum Sanctorum Geography
For decades, a townhouse at 177A Bleeker Street in New York's Greenwich Village, at the corner of Bleeker Street and Fenno Place, stood empty and abandoned until it was renovated by a front company for the Order of Kamar-Taj, a worldwide order of sorcerers. The house was originally built in the 1720s on a site where the Carnasee tribe of the Lenape people allegedly performed numerous rituals. Over time, the house got a reputation for being "haunted"; although it was often scheduled for demolition, it was never actually knocked down. The Order acquired it in 1862, and over the next few decades a series of sorcerers lived there in relative obscurity.
In recent years, the house again stood empty until the Order renovated it for Doctor Stephen Strange and Wong, two of the Order's sorcerers. Since the two moved in, rumors of the house being haunted have only grown.
The house itself is a place of power, and has a permanent mystical doorway connection to the Kamar-Taj monastery where the Order's grand master, the Ancient One, resides. In addition, the inside of the house is constantly changing; the house is larger on the inside than it is on the outside; the second and third floors of the house appear to have labyrinthine corridors and passageways which have dozens of doors and which can loop around on themselves. The number and contents of the rooms appear to change by themselves at random intervals, usually when no one is around to witness the changes. Despite this, there are rooms that remain relatively unchanged; it is possible the house itself is aware of its inhabitants and attempts to cater to their needs.
The building is protected from magical incursion by an intricate permanent spell which is interwoven with the house's own mystic energies; for as long as the building stands – and potentially even if the house should be destroyed while the energies remain – the protection spell will remain intact. This prevents foes from attacking the residents using magic, and even prevents anyone of hostile intent from entering the building.
There is a small courtyard in an alley behind the house branching off Fenno Place; this courtyard has an apple tree and a small gazebo for people to gather. Wong has stated that the gazebo itself is alive, but this statement is as yet unconfirmed.

Doctor Strange: Quite a place he's got here, isn't it? You know he calls it his--
Zelma Stanton: Sanctum Sanctorum, which is Latin for "Holy of Holies." A bit ostentatious for Bleeker Street, don't you think?

First Floor
The first floor contains the foyer, the main living room, the dining room, a library, and the kitchen. This floor is perhaps the most "normal" and changes the least over time.
Second Floor
This floor is dominated by at least four bedchambers, used by Strange, Wong, and Clea, with a fourth set aside for guest quarters. Other rooms and hallways on this floor come and go, with doors and windows that can lead to other places on Earth and other dimensions.
Third Floor
This floor is dominated by a meditation chamber which doubles as Strange's occult library. It is this room which has the large circular window with a mystic glyph as its panels, and houses The Book of the Vishanti, The Tome of Oshtur, and many other mystic tomes. Another nearby chamber houses the Orb of Agamotto, a large globe-sized crystal ball which can be used to pinpoint supernatural threats and view other locations in the Earth dimension and in others. Also on this floor is a chamber which has a number of mystic artifacts set up as a kind of museum; each artifact is protected by a spell which prevents anyone except Strange or Wong from touching them.
Basement
The basement of the Sanctum contains everything one would expect from such a residence: the water heater, circuit breaker, furnace, and the wine cellar. There are also rooms here which act as cells to contain magical threats. Like the second floor, the basement often has labyrinthine passages and doors to other locations.
Game Mechanical Details
The Sanctum Sanctorum is a high mana location/place of power. This reduces the threshold tally from ecocentric casting by a quarter and enables those without Magery to perform egocentric and exocentric magic.
Should the GM decide the house is in fact aware of its residents, it should have IQ 8, Will 18, and Per 12; those using The Fifth Attribute can make its Will 10 and QN 18. The "dread gazebo" in the rear courtyard, should Wong be correct in that it is also alive, has IQ 3, Will 10, Per 10, and if using The Fifth Attribute QN 14.
